CLOCK CONTRQL FOR TALKING-MACHINE RECORDS.

Application filed February, 1923.

To all whom it may concern:

Be it known that I, DOMENIOO BRUNELLI, a subject of the King of Italy, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in a Clock Control. for Talking-Machine Records, of which the following is a specification.

This invention appertains to a clock control for talking machine records. I

The principal object of the invention is to provide in combination, a conventional type of alarm clock positioned in an opening in the casing of a talking machine having a turn-table rotatably mounted therein, a lever in frictional contact with the rim of said turn-table and mechanism connecting the alarm mechanism of said clock with said lever so that when said alarm releases, at a predetermined time, said lever will be withdrawn from contact with said turntable permitting it to rotate.

Other objects will appear in the specilications and claims hereinafter contained.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following detail description and the accompanying drawings.

\Vhile the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, wherein Figure 1 is a front view of a clock of the conventional alarm type positioned in the casing of a talking machine, said casing being broken away;

Figure 2 is a sectional view on line 22 of Fig. 3, illustrating the clock and its connecting mechanism to controlthe rotation of the turn-table of a talking machine; and

Figure 3 is a plan view, with the lid raised, of the device shown in Fig. 2.

Like reference numerals refer to like parts throughout the several views.

Referring to the drawings in detail the numeral represents the casing of a talking machine provided with a lid 11 for access to the interior thereof. A turn-table 12 is rotatably mounted within said casing Serial No. 619,191.

10 and is adapted to be rotated by motor means (not shown), within the body of the casing 10.

A vertically extending lever 13 is mounted on a shaft 1 1 journaled in a bearing 1 1 mounted on the transverse arms 15-15 secured to the inwardly projecting extensions 1O".10 from the casing 10. The lever 13 extends through a. guide plate 24 and is positioned, substantially, parallel with the inner wall of the casing 10.

The lever 13 at its base has an integral extension 16 which extends laterally therefrom and at a slight downward angle. An opening 18 is provided in the outer terminal of said extension 16 in which is secured one end of a chain 17 the opposite end of said chain 17 being secured to a spool, or wheel 19.

A clock 20, of a conventional alarm type, having the clock face 26 and alarm setter 27 is suitably positioned in an opening in the front wall of the casing 10, substantially, centrally thereof, with the clock face 20 showing on the exterior of said casing.

An arm 21 is secured to the back of the clock 20, and is provided with an integral right angled extension 21. A shaft 22 is journaled in the extension 21 and the opposite end of said shaft 22 is journaled in the alarm mechanism in the back of the clock 20. A wheel 19 is mounted on said shaft 22 and is adapted to rotate therewith. To this wheel 19 is secured the lower end of the chain 17.

In operation :-The normal position of the lever 13 is as shown in solid lines in Fig. 2, the boss 23 on the said lever 13 impinging against the outer rim of the turn-table 12 and this frictional contact prevents the rotation of said turn-table 12 when the usual control thereof is released.

The alarm on the clock 20 is set to release at a predetermined time. When this time arrives the alarm is released rotating the shaft 22 which in turn rotates the wheel 19, mounted thereon, in the direction indicated by the arrow in Fig. 2, winding the chain 17 on said wheel 19 .which will cause the lever 13 to assume the position shown in dotted lines in Fig. 2, said lever 18 being adapted for such movement on the shaft 14. As soon as the boss 23 loses contact with the rim of the turn-table 12, said turn-table will rotate. When it is desired to again place the boss 23 in frictional contact with the horizontalharm, thegenerally, vertical, arm. a being adaptedtojprojecu above. the tllIHtH-vi rim of thevturn table- 12, the said lever 13; ispushed forward manually -,by means oii:

the knob 28 thereon until such contact is had. A spring 25 tends to limit the for- =Ward-mvement of-said leverll3. As thet Within the casing, a vertically sWingingbellcrank :lever plVOted wltlllll the casing near the turntable, saidbell-crank lever embody-v ing a generally vertical arm and a generally ble when in, theaotive position so; that itrnay be manually. operated, a, friction ilstopi. .ele-
